 This repo contains various examples of Azure Functions, for example a v1 http trigger, a v2 http trigger, a v2 blob trigger, blob copying, using a function's managed identity, delta tables, asyncio etc.
 
 The repo features functions of both programming model v1 and v2 – mainly v2 though. The repo also contains an Azure Devops pipeline (yaml) to deploy the underlying infrastructure (via Terraform) and the code to the function apps.
